So the code tells me that the processor was instructed to read from the address in RCX, and the dump shows me that the value is: RCX: f7ffc9000052c1d8 Current 64-bit x86 processors really only use 48-bit virtual addresses, which must begin with 0000 or ffff. So this address seems to have been corrupted: a single bit has changed. This could be caused by a software bug but it looks much more like a hardware fault. You may be able to confirm a RAM fault with memtest86+. Unfortunately it doesn't reliably find faults, and it doesn't particularly stress the CPU or other parts of the system that could also be at fault.
